apparently pacman checks irrelevant network drives for space

[sam-s]

Description / Steps to reproduce the issue

run pacman -Suy, accept Proceed with installation, then pacman runs fast except for the checking available disk space which is, apparently, done once for each package being installed (why?!) and is very slow.

Expected behavior

free disk space is a single system call, so it should be quite fast, unless network is involved.

Actual behavior

when installing, say, 7 packages, each of the 7 take a lot of time here:

(3/7) checking available disk space                          [#############------------------]  42%

You can disable that check by commenting out CheckSpace in /etc/pacman.conf file. More info man 5 pacman.conf https://man.archlinux.org/man/pacman.conf.5

Do you have any evidence that it is accessing network drives, or just that it is slow? #4176 I believe it is trying to stat all of the files the packages will install as part of this, and that's where the slowness is from, not any network access.

No, alas, no evidence.

The temporary work around is to disable pacman checking the disk space::

# Comment out "CheckSpace" in /etc/pacman.conf 
cd /etc && cp pacman.conf pacman.conf.bak && sed -i 's/^CheckSpace/#CheckSpace/' pacman.conf
