[pbs-devel] [PATCH proxmox-backup v2] etc: raise nofile soft limit for proxmox-backup-proxy

[Christian Ebner]

Since commit 86d5d073 ("GC: fix race with chunk upload/insert on s3
backends"), per-chunk file locks are acquired during phase 2 of
garbage collection for datastores backed by s3 object stores. This
however means that up to 1000 file locks might be held at once, which
can result in the limit of open file handles to be reached.

Therefore, bump the nolimit for the proxmox-backup-proxy in the systemd
service unit, while keeping the hard limit as defined in
/etc/systemd/system.conf.
