-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hey, I've personally ran into this before, but don't think that it is worth "fixing" in the current Pacman setup. User error is usually the cause of this, since an admin should always have adequate disk space before installing new packages. Preventing this is difficult, like Brendan said, available disk space may be taken by other causes when Pacman is running. Not to mention, some users like to split the filesystem into a multitude of partitions. However, I do have one unlikely suggestion that *could* combat this without much difficulty. I was thinking of this more to (partially) solve the issue of package updates being cut short by a hard shutdown. Basically, packages would be extracted to /var/lib/pacman/extract (or similair), and if extraction has not errored, files would be moved to their corresponding locations. This would keep the new, possibly incompatible files out of the system until they can almost instantly be moved over, except in the case of /var, or others being on different partitions. This has the drawback that the user must have roughly installed size*2 disk space free, since the old package and new package would both have to be extracted at once (I personally think this is almost a non-issue). The current Pacman implementation may already require that much free disk space, but I'm not sure. An alternative to the above is to create directories in the folders that the package extracts to, such as .pacextract in /bin. This would insure that all mounted partitions get a fast rename/move, mitigating potential data loss and allowing for perfect disk space checking. It could be done so that the .pacextract feature only runs on the bottom 2 or 3 directories (/usr, /usr/local, but not /usr/share/man/man8, which would have .pacextract/man8 in /usr/share/man), or on a predetermined set of directories in pacman.conf. I think my explanation might be a little confusing, so I will write it out in approximate psuedo-shell script. mkdir /usr/bin/.pacextract tar xf xz-4.999.8beta-1.pkg.tar.gz -C /usr/bin/.pacextract (with other flags so that tar only extracts the archive contents of /usr/bin) mv /usr/bin/.pacextract/* /usr/bin && rm -r /usr/bin/.pacextract The simpler (extract to /var/lib/pacman/extract) method does not offer the fast move when multiple partitions are used and perfect disk space utilization checking, but would be easier to code. Anyways, this idea is quite experimental. I do think it would thoroughly solve the disk space without too much difficulty, but I personally wouldn't use it soley for that.
