[SRU] Persistent dataset print strangely

[Didier Roche-Tolomelli]

[Impact]
 * When running When I run zsysctl show --full, the output of persistent datasets is garbagled, like:
Persistent Datasets:
                        - &{rpool/usr/local %!!(MISSING)s(bool=false) {/usr/local on %!!(MISSING)s(bool=true) %!!(MISSING)s(bool=false) %!!(MISSING)s(int=0) {inherited }} [] {%!!(MISSING)s(*zfs.Dataset=&{0x1fab700 1 map[1:{1594525151 none} 6:{yes none} 13:{/usr/local inherited} 27:{rpool/usr/local none} 28:{on default}] []})}}
                        - &{rpool/var/games %!!(MISSING)s(bool=false) {/var/games on %!!(MISSING)s(bool=true) %!!(MISSING)s(bool=false) %!!(MISSING)s(int=0) {inherited }} [] {%!!(MISSING)s(*zfs.Dataset=&{0x1b96680 1 map[1:{1594525151 none} 6:{yes none} 13:{/var/games inherited} 27:{rpool/var/games none} 28:{on default}] []})}}
                        - &{rpool/var/mail %!!(MISSING)s(bool=false) {/var/mail on %!!(MISSING)s(bool=true) %!!(MISSING)s(bool=false) %!!(MISSING)s(int=0) {inherited }} [] {%!!(MISSING)s(*zfs.Dataset=&{0x1beff10 1 map[1:{1594525151 none} 6:{yes none} 13:{/var/mail inherited} 27:{rpool/var/mail none} 28:{on default}] []})}}

[Test Case]
 * After installing new version, run zsysctl show --full and check the output of persistent datasets
Those should be of the form:
Persistent Datasets:
  - rpool/boot/grub

[Regression Potential]
 * The code impact is on the output formatting, which then can be less readable than today.
 * Note that i18n is impacted (due to the \t which was invalid here), but in practice, this string isn’t translated.

Hello Didier, or anyone else affected,

Accepted zsys into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/zsys/0.4.8 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-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. 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.
