Closing 1 doesn't change the fact that it is still an issue om the server side. If for some reason the PXE images would be unavailable from the server, then the same bug would apply to maas-import-pxe-files, or to maas-import-ephemerals for such case. That's even if we didn't have the support for squashfs. Either way, the bug reported by Diogo was only seen in the lab that maybe had bad mirrors, because it was proven that at other locations the bug wasn't present.

2 is a bug which is unrelated with squashfs support because this bug affects maas-import-pxe-files and maas-import-ephemerals. Removing the support doesn't fix it, because the bug will still be present even if there was no squashfs support. In fact, there's was a bug in MAAS that affected installations using squashfs, not because of the support but because of a bug in MAAS.

3. Simple fix.

2 minute to be exact.

Right, but I was just pointing out that it isn't the only thing untested that maas ships, is it? However, its been placed as a strong reason for dropping the support.

Exactly, number of bugs is not a measure of quality; yet, the statement for removal of the feature is based on "disproportionate number of bugs" and "doesn't work by most/all accounts", which are both based and backed by 3 bug reports linked to this MP. However, both statements IMHO are incorrect.
