Package: devscripts
Version: 2.20.5
Severity: normal
Dear Maintainer,
any chrooted run debrepro fails on cleanup with s.th. like:
---
rm: cannot remove '/tmp/debrepro.WdTfiXpiIP/second/source': Device or resource
busy
---
This is due to fusermount -u failing w/
---
fusermount: failed to mark mounts private: Invalid argument
---
fusermount in a check prior to the umount runs
---
res = mount("", "/", "", MS_PRIVATE | MS_REC, NULL);
---
This *seems* to fail in chroots "since some kernel versions";
i.e., definitely fails w/ linux 5.* (bullseye), definitely used
to work with linux 4.19.* (buster).
A simple "umount" otoh still works for me like a charm -- "working for me"-style
patch attached, but there is no real wisdom in it ;).
It really seems to be a generic problem, but I'd still love someone to re-test
this in case it's a PP after all...
Thanks!
Stephan

Subject: [PATCH] debrepro.sh: Use 'umount', not 'fusermount -u' (fixes umount
in chroot).
fusermount in a check prior to the umount runs
---
res = mount("", "/", "", MS_PRIVATE | MS_REC, NULL);
---
This seems to fail in chroots "since some kernel versions";
i.e., definitely fails w/ linux 5.* (bullseye), definitely used
to work with linux 4.19.* (buster).
