difference between netinstall and upgrade via ftp

hi,

i do not understand what the difference between netinstall and ftp update is if i use system reset-configuration. are not both really restoring the default config ?

i am asking because in one of our support cases i was asked to do a netinstall to fix a problem. can anyone explain please ?

regards
Jan

Netinstall re-installs the software. FTP upgrade just upgrades it. There is a lot more in Netinstall.
