Hi,
since live-helper 1.0.6, and also in LH2, I'm getting a very long
content in LH_BOOTAPPEND_INSTALL because LH_BOOTAPPEND_LIVE is
expanded each time "lh config" is executed.
For example:
$ lh config
$ lh config --bootappend-live "locale=pt keyb=pt utc=no
timezone=Europe/Lisbon quickreboot quiet"
$ lh config --binary-images usb-hdd
$ lh_config --linux-flavours "686"
At this point the last "lh config" has expanded the content of the
variable LH_BOOTAPPEND_LIVE inside the line "LH_BOOTAPPEND_INSTALL="
-- \${LH_BOOTAPPEND_LIVE}" (done in line 840 in functions/defaults.sh)
and does it each time "lh config" is executed. "cdrom-detect/try-usb"
is getting duplicated too.
In live-helper 1.0.5 and earlier versions, LH_BOOTAPPEND_INSTALL was
only updated if it was unset.
To avoid a regression on this, I'd like to propose this patch. The
main changes are the following: before starting to update
LH_BOOTAPPEND_INSTALL, it removes the "LH_BOOTAPPEND_LIVE content from
it to avoid duplications. It also removes any previous
"cdrom-detect/try-usb" option before applying another one. Also,
leading/trailing spaces are removed.
Please remove any comments that you consider superfluous and make any
necessary changes to make it simpler.
Regards,
Rui M. P. Bernardo
