[Bug 1898081] Re: cephadm.postinst uses hard coded path /home/cephadm/

[ben simons]

Alternatively, I was able to get it to work by creating a symbolic link
to the existing `.ssh` directory,

`sudo ln -s /home/cephadm/.ssh /var/lib/cephadm/.ssh`

Title:
  cephadm.postinst uses hard coded path /home/cephadm/

Status in ceph package in Ubuntu:
  New

Bug description:
  Hello all,

  ### release ###
  lsb_release -rd
  #Description:   Ubuntu 20.04.1 LTS
  #Release:       20.04

  ### package version ###
  apt-cache policy cephadm
  #cephadm:
  #  Installed: 15.2.3-0ubuntu0.20.04.2
  #  Candidate: 15.2.3-0ubuntu0.20.04.2
  #  Version table:

  ### expected ###
  /var/lib/dpkg/info/cephadm.postinst using $HOME from previously created new user 'cephadm' to prepare ˜cephadm/.ssh/authorized_keys

  ### what happened instead ###
  /var/lib/dpkg/info/cephadm.postinst uses hard coded path /home/cephadm complaining with
    "mkdir: cannot create directory ‘/home/cephadm/.ssh’: No such file or directory"
  if /etc/adduser.conf:DHOME was modified.

  ### Notes ###
  While installing cephadm(8) we get
    "mkdir: cannot create directory ‘/home/cephadm/.ssh’: No such file or directory"
  due to hard coded "/home/cephadm/.ssh" in /var/lib/dpkg/info/cephadm.postinst .
  Previously /var/lib/dpkg/info/cephadm.postinst uses adduser(8), honoring
  /etc/adduser.conf:DHOME - which may be changed from it's default "/home".

  Modified /var/lib/dpkg/info/cephadm.postinst attached.

  
  Thanks & best regards
  Uwe
