Eelco Dolstra	d6d930a975	* Bug fix: deleting the old links didn't work properly.	2003-04-25 15:20:05 +00:00
Eelco Dolstra	243370bc52	* nix-switch now removes the link to the previously activated system ... package as a root of the garbage collector, unless `--keep' is specified.	2003-04-24 11:43:11 +00:00
Eelco Dolstra	30a6122f80	* When we activate a descriptor in nix-switch, remember its hash. ... This allows us to find out all `live' packages on the system by doing nix closure $(cat /nix/var/nix/links/*.hash) which will print out the activated configurations and all packages referenced by them. We could then garbage collect unused packages by deleting the difference between `nix listinst' and the set returned by `nix closure ...'.	2003-04-09 12:46:44 +00:00
Eelco Dolstra	aa8fda4b54	* We no longer use nix-populate standalone, rather we use it as a ... build action for `system' packages (like system.fix) that have dependencies on all packages we want to activate. So the command sequence to switch to a new activation configuration of the system would be: $ fix -i .../fixdescriptors/system.fix ... system.fix -> 89cf4713b37cc66989304abeb9ea189f $ nix-switch 89cf4713b37cc66989304abeb9ea189f * A nix-profile.sh script that can be included in .bashrc.	2003-04-09 12:26:48 +00:00
