It's impossible, since it doesn't only depends on the installed |
| 21 |
software. It also depends on many other factors: |
| 22 |
|
| 23 |
1.- the time when you did the last update |
| 24 |
2.- the number of packages that has updates, which is not always |
| 25 |
related to the number of packages you have installed, but to |
| 26 |
_what_ packages do you have installed. Some packages doesn't |
| 27 |
get updates too frequently, while others change a lot. |
| 28 |
3.- external factors, like overlays |
| 29 |
|
| 30 |
It just depends on _what_ needs to be updated. |
| 31 |
|
| 32 |
I can give you a few hints, though. Most packages can compile in |
| 33 |
a reasonable amount of time. Some specific packages will take |
| 34 |
longer to compile. You will learn to identify them with the time. |
| 35 |
For example, openoffice if probably the largest, and can take from |
| 36 |
several hours up to days, depending on your hardware. Some kde |
| 37 |
packages are big, like kmail. Qt or Gtk as intermediate things. |
| 38 |
Glibc and gcc can take a lot of time, as xorg-server, for example. |
| 39 |
|
| 40 |
Whe you are doing the update, you have to know a few things. On first |
| 41 |
place, use this instead of your command above: |
| 42 |
|
| 43 |
merge --update --deep --newuse --verbose --ask world |
| 44 |
|
| 45 |
This will present you with a list of the packages that will be |
| 46 |
updated, that way, you know how many packages are going to be |
| 47 |
updated, but, more important, you will know _what_ packages will |
| 48 |
be merged. |
| 49 |
|
| 50 |
The depclean and revdep steps shouldn't be too time consuming |
| 51 |
on a sane system. So, if you use them regularly, those steps |
| 52 |
will not rob much of your time. The sync step depends on your |
| 53 |
connection speed and the time since your last sync. It can take |
| 54 |
a few minutes on a fast connection if your tree is up to date. |
| 55 |
But it can take a day on a 56k modem if you tree is empty or |
| 56 |
way too outdated. |
