Thanks very much for the tip! That does just what I asked for.
But I think maybe I got ahead of myself, and didn't ask the right
question ;) I have been using Linux (Slackware/RedHat/LFS) for a
long time, but I am pretty new to the flash/SD/TS-LINUX/Debian arenas
I am developing a WiFi geo-logger that will also control some simple
local hardware. It will operate on battery power, and is likely to
have the power cycled without warning.
The hardware is a TS-7260 with the stock USB WiFi, SD card with Debian
development system, with a USB GPS.
For the fielded product:
Required System Services: Apache, Samba, gpsd, syslog, maybe a very
few others.
Requires pretty fast reboot after power cycling: say, less than 30 sec
My question is:
What is the best choice, in terms of a bulletproof final product, for
a boot device? Kernel?
1. The power cycle and reboot time requirements seem to rule out
booting from an EXT2 partition on the SD Card, due to fsck's execution
time.
2. The process for booting from the SD Card on the TS-7260 seems a bit
daunting, but if one could use a journaling file system such as EXT3,
then perhaps it is worth the effort.
3. One could boot from flash with the root file system on flash, and
then fsck the EXT2 partition on the SD card in the background.
My immediate question is: Where/How to install Samba for use in the
fielded system? If I chroot to the SD Card, I can use get-apt to
install Samba, but that will install it in the file system on the SC
Card (I think).
As I said in the original question: I know there must be some
(relatively) simple way to do this, I am just a little unfamiliar with
the terrain.
As I believe I have made clear ;)
