[pve-devel] [PATCH] fix #5869: d/postinst: do not fail if ifreload fails on first install

[Stoiko Ivanov]

erroring out here will not help getting a running network, therefore
just log a warning.

Tested the original reporters case (running in a debootstrap) with:
```
mmdebstrap \
 --variant=minbase \
 --include=/tmp/ifupdown2_3.2.0-1+pmx10_all.deb \
 --hook-dir=/usr/share/mmdebstrap/hooks/file-mirror-automount \
 bookworm \
 ./bookworm-amd64.tar.zst
```
ran through our install on plain debian guide:
https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm
with this package in a local repository to check for regressions

adding the reference to the commit that introduced the reload on
first-install, as this got shifted around a bit and it took me too
long to see that we did not want to error out here on purpose
