[0rinsb3lt]

Fixed pull request to just include pbzip2

[tritonas00]

please edit:

$BRmcore to "$BRmcore"
${BRreadopts} to "$BRreadopts"

and its ok.

of course we need to add extra check for pbizp2 package existence and update the help page and gui

i will apply the PR and do the extra work when i have my laptop

[0rinsb3lt]

I used ${BRreadopts} because it wouldn't work with just the quotes or with quotes and brackets due to the multiple hyphens. I have tested both conditions.

will update $BRmcore to "$BRmcore"

[tritonas00]

lines 500-501 are wrong and update please BRreadopts also

[0rinsb3lt]

I've tested "$BRreadopts" but it doesn't work. It'll spit out errors.
Probably be better to convert it to an array like BR_MAIN_OPTS
Due to the way bash handles passing variables to commands as parameters with spaces.

Ok then

[tritonas00]

please quote BRreadopts array in read_archive and convert BR_MAIN_OPTS to array also here https://github.com/tritonas00/system-tar-and-restore/blob/master/star.sh#L909 and test
