1. FreeDOS have no issues with config.sys size, because it not loads it into
memory completely, but reread line-by-line (just like batch files) at
each pass.
2. Yes, mangling drive mappings will cause troubles with config.sys (like
with .BAT files processing), unless you place copy of config.sys (or
fdconfig.sys) into new drive (like with .BAT files processing). [And I
not change there anything.]
Difference with .bat files processing is that config.sys is not
open/closed for each line, thus drive mapping issue will be seen only
after current pass. If you swap letters at INSTALL= stage (last pass),
then you will see no troubles.

1. There is SSWAP.EXE in Stacker package, but this is .EXE file, not driver.
2. Stacker preload driver (which copied into dblspace.bin) also changes
drive letters (as pointed by stacker.ini), but this happens when MS-DOS
loads this driver before processing config.sys. Under FreeDOS preload
drivers are not supported.

No.
PS: Steffer, when you answer to my letter in the freedos-freecom about
issues with environment in FreeCOM?
