[Bug 1579457] Re: ubiquity must NOT format a valid SWAP partition on manual partitioning

[Dan Bungert]

It is possible to re-partition the disk and preserve the partition
label.  On Subiquity installers this will do the right thing, we
preserve the partition label unless we've been told not to.

If an interested community member wants to address this that would be a
useful improvement for Ubiquity installers, and for Subiquity installers
this should be resolved.

Title:
  ubiquity must NOT format a valid SWAP partition on manual partitioning

Status in ubiquity package in Ubuntu:
  Triaged

Bug description:
  On manual partitioning, ubiquity systematically formats the SWAP
  partition, even if this SWAP partition is perfectly valid.

  For the SWAP partition, this unnecessary formatting modifies its
  filesystem UUID and blanks its filesystem LABEL.

  This BREAKS COMPATIBILITY with other distribution(s) installed on the
  same machine, whose '/etc/fstab' reference the SWAP partition by UUID
  or LABEL.

  If fact, ubiquity must NOT format a valid SWAP partition.

  This issue is :
  -  similar to the 3rd item (left uncorrected) of bug #83166
  -  related to bug #533618
