[Bug 1820604] Re: curtin fails to find itself in subiquity snap

[Dimitri John Ledkov]

** Also affects: livecd-rootfs (Ubuntu)
   Importance: Undecided
       Status: New

** Changed in: curtin
       Status: Incomplete => Invalid

** Description changed:

- sudo snap install subiquity --classic
- export SNAP=/snap/subiquity/664
- export PYTHONPATH=/snap/subiquity/664/lib/python3.6/site-packages/ 
+ serial-subiquity at .service runs very differently to the tty1 subiquity.
  
- $ /snap/subiquity/664/usr/bin/python3 -c 'import curtin.util; print(curtin.util.get_paths())'
- {'curtin_exe': None,
-  'lib': '/snap/subiquity/664/lib/python3.6/site-packages/curtin',
-  'helpers': '/snap/subiquity/664/usr/lib/curtin/helpers'}
+ In seiral-subiquity@ case, it doesn't block starting on snapd as it
+ doesn't use /usr/bin/snap run.
  
- I think this is due to curtin getting installed as bin/curtin, not as
- usr/bin/curtin inside the subiquity snap.
+ Also, it doesn't execute subiquity.subiquity-service script, meaning
+ that PATH setting there is not exported, causing troubles for curtin to
+ reexec itself, or to find the right python in $PATH.
  
- Note that:
  
- $ /snap/subiquity/664/usr/bin/python3 -c 'import curtin.util; print(curtin.util._installed_file_path("usr/bin/curtin"))'
- None
+ Fix that in both livecd-rootfs & subiquity.
  
- yet
- 
- /snap/subiquity/664/usr/bin/python3 -c 'import curtin.util; print(curtin.util._installed_file_path("bin/curtin"))'
- /snap/subiquity/664/bin/curtin <- winner
- 
- I don't know if we should be forcing subiquity snapcraft to install
- curtin into usr/bin, or if curtin code should be tweaked to try to
- detect curtin in $SNAP/bin/curtin.
- 
- Or like if we should append $SNAP/bin to $PATH.

Bug description:
  serial-subiquity at .service runs very differently to the tty1 subiquity.

  In seiral-subiquity@ case, it doesn't block starting on snapd as it
  doesn't use /usr/bin/snap run.

  Also, it doesn't execute subiquity.subiquity-service script, meaning
  that PATH setting there is not exported, causing troubles for curtin
  to reexec itself, or to find the right python in $PATH.

  
  Fix that in both livecd-rootfs & subiquity.
