Matching installed programs quickly and easily [Solved]

[powemi]

First off, Hello everyone. This is my first post on Sabayon Forums. I have been running some form of Linux since SuSe 9 back when I was in high school. This by far does not make a genius at this OS. I have spent a lot of time learning and just going through forums in order to make my life a little easier with Linux. I am not a programmer or engineer, I am a Chef that is back to school now for Economics and International Business with plans to go on to a J.D. I run Linux mainly because Windows and OS X suck (while I do run all three on my Mac Pro I have not booted Windows or OS X in over a year.)

On to my question. I have had Sabayon on my Lenovo X230 for a couple months and was extremely impressed by how much speed I gained from having Ubuntu, Fedora on it before. Having this speed increase I installed Sabayon on my Mac Pro and got rid of my Fedora install. Now I have Sabayon on both my main machines. Being new to Equo (yes I have read the Newbie Page https://wiki.sabayon.org/?title=En:Entropy, I have now got both my machines up to date but only my laptop has all my programs on it. Is there a file in Entropy that I can transfer to my Mac Pro from my laptop that would once Equo is updated again will installed all the same programs?

While I have all ready started installing the programs one by one on the desktop I thought this being Linux and all there was probably a easier way to match programs. Can't imagine there is not since it would be a huge waste of time for IT to install everything one by one in a corporate environment. I could be wrong though.

Thanks in advance for any help or advice.

hmmmmm, off the top of my head you can use equery to generate a list of every thing installed, but than you would have to go thru it and edit out stuff so you weren't reinstalling absolutely every thing. something like equery list "*" > packages should get u a text file to view. Take some time to edit but than you could feed it to equo.

Thanks for that. Took that and made a .txt file on each computer and used Diff which gave me a quick reference of the packages that were needed for the new install, as I usually forget about all the small Cran and Latex add ons that I have installed. Major apps are easier to remember since I use them on a daily basis.

While it is not as automatic as I would expect for something that needs to happen in the world of computers it still gets the job done.

Now both systems are equal on the software side of things.

Thanks again

you can generate a database backup of entropy

Code: Select all

# equo rescue backup

this backup will be stored in /var/lib/entropy/client/database/{x86,amd64} named entropy_backup___system__<something>.backup.bz2

copy this backup in the same path in another machine then

Code: Select all

# equo rescue restore

follow the istructions to restore backup and

Code: Select all

#  equo upgrade --empty --deep --bdeps && equo deptest && equo libtest

(don't update 'cause will overwrite your database backup)

if that isn't in the wiki it should be

[sabayonino]

if that isn't in the wiki it should be

uhm ... I think this feature isn' complete

example :

now my sab is ok. I make a backup of entropy

Code: Select all

# equo rescue backup

now I install "amanda" (app-backup/amanda)

Code: Select all

# equo i app-backup/amanda

and its deps

Code: Select all

app-arch/mt-st-1.1|0
╠  ## [N] [sabayonlinux.org] app-arch/sharutils-4.14|0
╠  ## [N] [sabayonlinux.org] app-crypt/aespipe-2.4c|0
╠  ## [N] [sabayonlinux.org] app-arch/dump-0.4.44-r1|0
╠  ## [N] [sabayonlinux.org] sys-block/mtx-1.3.12|0
╠  ## [N] [sabayonlinux.org] app-backup/amanda-3.3.3-r1|1


for some reason my system breaks and decide to restore previous backup (amanda isn't include in entropy backup)

Code: Select all

# equo rescue restore
[...] <restoring>
# equo upgrade --deep --bdeps --deep && equo deptest && equo libtest


Code: Select all

 equo s amanda

amanda doesn't match .
ok my backup is restored

entropy doesn't find any (extra) libraries installed by amanda but libraries are still present even if amanda isn't installed

Code: Select all

# # ls /usr/lib | grep amanda
amanda


looking for some option(s) to solve this

maybe I'll file a bug

[wolfden]

I would think you would have to run

Code: Select all

# equo rescue backup

each time you made a change, otherwise how it see the changes?

Backup entropy database

Code: Select all

# equo rescue backup

Restore a entropy backup

Code: Select all

# equo rescue restore

see

Code: Select all

# equo rescue --help

The changes are made database only not for all packages,libraries and executables and other files installed before or after a backup. thye're keeped in the filsystem
I would like to see a clenup option for orphan files (like a rsync comand or something else)

[sabayonino]

you can try this also :

make a backup of entropy datatabse

Code: Select all

# equo rescue backup

make a quickpkg of all package installed and store them where you want (example external hard-drive mounted on /media/packages)

Code: Select all

# equo pkg quickpkg --savedir=/media/packages `equo query list installed`

(without --savedir option all packages will be stored in /var/tmp/entropy by default)

then copy entropy database saved in /var/lib/entropy/client/database/{amd64,x86}/<something>_backup.bz2 to other machine(s) in the same path

in other machine mount external hard-drive (or setup an NFS direcotry)

edit /etc/entropy/repositories.conf.d/entropy_<repository-id> (where <repository-id> is the repository in use {sabayonlinux.org,sabayon-weekly,sabayon-limbo})

add this line at the end of the file :

Code: Select all

pkg = file:///<dir>/<packages>      # /<dir>/<packages> = mount point of external drive or NFS directory)

restore backup

Code: Select all

# equo rescue restore

Code: Select all

# equo upgrade --deep --bdeps --empty

all packages will be downloaded from your external-harddrive or local mount poit




see

Code: Select all

# equo pkg --help

[sabayonino]

I performed the follow commands to create a fully installed packages list (and binary packages tbz2)and restore them into fresh install

Backup entropy database

Code: Select all

# equo rescue backup

(see /var/lib/entropy/client/database/<arch>/ )

make packages

Code: Select all

# equo pkg quickpkg --savedir=/where/to/storage/packages   $(equo query list --verbose installed | cut -d" " -f7)

(--savedir could be an external hdd)

To restore these packages in a fresh install :

Mount external HDD where all packages are stored (example > /mnt/HDD )

Edit repository file (/etc/entropy/repositoires.conf.d/entropy_<repository-id> ) and add at the bottom :

Code: Select all

# pkg = file:///mnt/HDD

Copy entropy_backup in the same path and restore backup

Code: Select all

# equo rescue restore

(follow the istructions)

then upgrade (not update ! )

Code: Select all

# equo upgrade --purge --ask

Good luck !
