Subject: [PATCH] nspawn: ignore EEXIST when creating mount point
|
|
|
|
A combination of commits f3c80515c and 79d80fc14 cause nspawn to
|
|
silently fail with a commandline such as:
|
|
|
|
# systemd-nspawn -D /build/extra-x86_64 --bind=/usr
|
|
|
|
strace shows the culprit:
|
|
|
|
[pid 27868] writev(2, [{"Failed to create mount point /build/extra-x86_64/usr: File exists", 82}, {"\n", 1}], 2) = 83
|
|
|
|
(cherry picked from commit 1ab19cb167b32967556eefd8f6d3df0e3de7d67d)
