[Bug 1902891] Re: "Too many levels of symbolic links” error when using systemd to mount sshfs

[Brian Murray]

Hello Sami, or anyone else affected,

Accepted systemd into groovy-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/246.6-1ubuntu1.4 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
groovy to verification-done-groovy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-groovy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: systemd (Ubuntu Groovy)
       Status: In Progress => Fix Committed

** Tags added: verification-needed verification-needed-groovy

Bug description:
  [impact]

  sshfs mount configured in fstab fails with 'too many levels of
  symbolic links'

  [test case]

  configure a sshfs mount in fstab using a remote system where the local
  user performing the mount (usually, root) does not have the remote
  host ssh key in its known hosts db

  then attempt to access any files under the mount, and check the
  journal

  see original description for more detail

  [regression potential]

  any regression would likely cause systemd-mounted filesystem(s) to
  fail to be correctly mounted

  [scope]

  this is needed for g and earlier

  this is fixed upstream with commit
  2fa0bd7d57863dffda89190a70a83c51bd7d114a which is included in v247, so
  this is fixed in h and later

  I have asked question at askubuntu about "Too many levels of symbolic
  links” error when trying to use systemd to mount sshfs
  (https://askubuntu.com/questions/1286375/too-many-levels-of-symbolic-
  links-error-when-using-systemd)

  I have not got any responses, so I am submitting a bug report. If this
  is not a bug, please advice how to mount sshfs share with systemd.
