Subject: [PATCH] libremakepkg: fix building packages requring a rw startdir
Several packages require a read-write startdir:
- Some packages have a pkgver that is computed dynamically
through a pkgver function. This is the case for many packages
using git repositories. At the end of the package build, the
pkgver is automatically updated in the PKGBUILD, however,
without that fix that fails with libremakepkg as the PKGBUILD
was set read-only.
- Some packages like linux-libre are modifying the install=
script. This is done by creating a temporary install script
in the startdir that is then modified with sed. Once this is
done that install script is then dynamically selected.
As this also require to have read-write access to the
startdir to be read-write it fails to build the package if
it's not the case.
In both cases it's possible to modify the PKGBUILDs to
workaround the issue, however the Arch Linux distribution has
a read-write startdir, and modifying each affected packages
would significatively increase the cost (in time and efforts)
of maintaining Parabola.
This was broken by the following commit:
646ac02 libremakepkg,chcleanup: Be stricter about network access
Thanks to elibrokeit on the #parabola IRC channel on Freenode
for helping me identifying the cause of read-only mounts in
libremakepkg.
