Trying to remove nano 'cause I'm using vim.
Entropy tells me that can't be removed 'cause it's a vital package for the system. I won't use --force-system option if nano is a system package (even if I know it won't be a bad thing after all), but I'd like to know why nano is a system package.
Never saw a distro - until now - where nano can't be removed peacefully :shock:

I'm obliged to keep both editors?

Code: Select all: equery d nano

Output:

* These packages depend on nano:
virtual/editor-0 (app-editors/nano)

checking /usr/portage/virtual/editor/editor-0.ebuild shows that this virtual package can be satisfied by pretty much any editor. I think that the virtual dependency is captured when the editor-0 package is built on sabayon servers. This is why removing it would remove virtual/editor which is the vital package here. Well even after having installed vim and by using emerge, it still complain that nano is a vital package. But we are confident enough that vim can satisfy virtual/editor's requirements, aren't we?

So, IF you have your portage already up and running, you could "fix" this this way:

Code: Select all: equo install vim emerge --depclean --verbose --ask nano emerge -avt virtual/editor equo rescue spmsync equo mask virtual/editor

now let's take a look at vim's revdeps (you need gentoolkit installed):

Code: Select all: equery d vim | grep editor

Output:

virtual/editor-0

As you can see, virtual/editor now depends on vim.

Ciao matteo :mrgreen:

list available your editor profile(s) (..and change editor variable) :

Code: Select all: # eselect editor list

Code: Select all: ... eselect editor list Available targets for the EDITOR variable: [1] /bin/nano [2] /bin/ed [3] /usr/bin/ex [4] /usr/bin/vi [ ] (free form)

Set your favourite editor

Code: Select all: # eselect editor set 4 Setting EDITOR to /usr/bin/vi ... Run ". /etc/profile" to update the variable in your shell

Code: Select all: # . /etc/profile
