Package: arcboot-installer Version: svn 30/3/2004 Severity: wishlist Tags: patch
The installation should remind users to set the appropriate PROM variables after rebooting. Otherwise, they could easily get stuck with an unbootable system. The following patch should do the trick. Since the PROM needs SCSI bus/ID/LUN identifiers, some /proc parsing is required. That section has been tested and works properly, but the debconf call is broken in some way that I hope is obvious to others. (My debconf knowledge is, uh, minimal.) -- Nicholas Breen [EMAIL PROTECTED] diff -Nru arcboot-installer.svn/debian/arcboot-installer.postinst arcboot-installer/debian/arcboot-installer.postinst --- arcboot-installer.svn/debian/arcboot-installer.postinst 2004-03-30 14:10:45.000000000 -0500 +++ arcboot-installer/debian/arcboot-installer.postinst 2004-03-30 15:35:06.000000000 -0500 @@ -75,3 +75,22 @@ # exit 1 # fi #fi + +# Suggest the necessary PROM variables that will need to be set before the +# system can be booted. + +abootmajor=`ls -l $defaultbootdev | cut -c34-37 | sed 's/ //g'` +abootminor=`ls -l $defaultbootdev | cut -c39-42 | sed 's/ //g'` +arootmajor=`ls -l $rootfs | cut -c34-37 | sed 's/ //g'` +arootminor=`ls -l $rootfs | cut -c39-42 | sed 's/ //g'` + +ABOOTBUS=`grep "^\ \+$abootmajor\ \+$abootminor\ \+" /proc/partitions | cut -d/ -f3 | sed 's/^bus//'` +ABOOTID=`grep "^\ \+$abootmajor\ \+$abootminor\ \+" /proc/partitions | cut -d/ -f4 | sed 's/^target//'` +ABOOTLUN=`grep "^\ \+$abootmajor\ \+$abootminor\ \+" /proc/partitions | cut -d/ -f5 | sed 's/^lun//'` +AROOTBUS=`grep "^\ \+$arootmajor\ \+$arootminor\ \+" /proc/partitions | cut -d/ -f3 | sed 's/^bus//'` +AROOTID=`grep "^\ \+$arootmajor\ \+$arootminor\ \+" /proc/partitions | cut -d/ -f4 | sed 's/^target//'` +AROOTLUN=`grep "^\ \+$arootmajor\ \+$arootminor\ \+" /proc/partitions | cut -d/ -f5 | sed 's/^lun//'` +AROOTPART=$((`echo $rootfs | sed 's/^[a-z\/]\+//'` - 1)) + +db_input high arcboot-installer/prom-variables || true +db_go || true diff -Nru arcboot-installer.svn/debian/arcboot-installer.templates arcboot-installer/debian/arcboot-installer.templates --- arcboot-installer.svn/debian/arcboot-installer.templates 2004-03-30 14:10:45.000000000 -0500 +++ arcboot-installer/debian/arcboot-installer.templates 2004-03-30 15:29:34.000000000 -0500 @@ -23,3 +23,22 @@ The arcboot package failed to install into /target/.
