Oberon/A2/mya2

#!/bin/bash # A script to start UnixAos or repository based A2 with a working # directory which can be in a removable flash store. # A flash store is accommodated in multiple machines by copying # machine specific configurations into Configuration.XML and # Oberon.Text. # # Conditions for this script to work. # * The volume containing the working files has a reliable identity. # Contemporary systems recognize a UUID. Refer to lsblk and blkid # * If /etc/fstab has a specification for the working volume, consider # consistency with the names and mount command below. Eg. # UUID=40d81923-8f9d-4964-b724-87bcf2731432a /home/me/A ext2 defaults,user,users,exec,noauto 0 0 # * The user can fsck the working filesystem. # A line such as the following may be required in /etc/sudoers.d/sudoers. # me mycomputer = NOPASSWD: /sbin/fsck # Test fsck interactively. # * If the working volume is removeable, the user can mount it. # Note the user option in /etc/fstab. # * Prior to revision 10272, UnixAos attempts to create the link # <workingDirectory>/.aoshome to /usr/aos but the FAT file system # doesn't provide links.
