Define sda as the smallest disk

[Diego Zuccato]

I think there's a bug (well, a missing piece) in 99-disklist.sh: egrep 
ignores SCSI disk, considering just ATA and NVME.

If it can be useful, I also modified the script to look into 
99-disklist.d for hostname-specific configs (I prefer having separate 
files instead of embedding in a bigger one):

-8<-- 99-disklist -8<--
#! /bin/bash

mydisks() {

     find $* -type l -printf "%f %l\n" | grep -Pv 
'^md|-part\d|^wwn-|^nvme-eui|^nvme-nvme' | egrep '^scsi|^ata|^nvme' | 
sed -e 's#.*/##g'| tr '\n' ' '
}

# This is really important, because we use shell globbing for creating 
the list of disks
cd /dev/disk/by-id || echo Cannot get disk information

filter='nvme*'

if [ -f $0.d/$HOSTNAME ] ; then
     # Source host-specific list.
     # Can define a new list or just override filter
     . $0.d/$HOSTNAME
fi

if [ -z $newlist ]; then
     newlist=$(mydisks $filter* )
fi

if [ -n "$newlist" ]; then
     echo New disklist: $newlist
     echo disklist=\"$newlist\" >> $LOGDIR/additional.var
fi
-8<--
Note the missing .sh extension.

The 99-disklist.d/$HOSTNAME file is just:
-8<--
#!/bin/bash
filter='scsi-*'
# or
#newlist='sda'
-8<--

HiH.
