symbolic links for --profile argument

symbolic links for --profile argument

[Fulbert]

Hello and thanks for visiting my question !

It is a stupid one, but just to be sure :

Given

~~~{.bash}
$ readlink ~/.guix-profile
/var/guix/profiles/per-user/fulbert/guix-profile

$ readlink -f ~/.guix-profile
/gnu/store/2sj11f64c9cgw40gkjy024vjl688zp7k-profile
~~~{end}

Will the following commands produce exactly the same result ?

~~~{.bash}
$ guix package -m ~/default.scm
$ guix package -m ~/default.scm -p ~/.guix-profile
$ guix package -m ~/default.scm -p /var/guix/profiles/per-user/fulbert/guix-profile
$ guix package -m ~/default.scm -p /gnu/store/2sj11f64c9cgw40gkjy024vjl688zp7k-profile
~~~{end}

… and more generally, any guix command taking a `--profile` argument ?

Hi,

The first and third commands are equivalent. I believe the second command will replace .guix-profile with a symlink to .guix-profile-1 which will link to the store. The last command should fail, because you can't create a store item that way.

I think guix environment --profile will create a profile and symlink directly to the store, without creating generations. Guix package and its aliases (update, remove, install) as well as guix pull create a generation, so their --profile option has the same behavior.

HTH!
