<div dir="ltr"><font face="Tahoma" color="#000000" size="2">Hi all,</font></div>
<div dir="ltr"><font face="Tahoma" size="2"> </font></div>
<div dir="ltr"><font face="Tahoma" size="2">I'm a student here in Germany and my Prof. wants me to do a brief presentation about developing file systems and managing file system development.</font></div>
<div dir="ltr"><font face="Tahoma" size="2">I searched across the internet, but information about that is really hard to find.</font></div>
<div dir="ltr"><font face="Tahoma" size="2"> </font></div>
<div dir="ltr"><font face="Tahoma" size="2">So I put some questions together. If you don't mind I'd like to ask you if you could answer them briefly.</font></div>
<div dir="ltr"><font face="Tahoma" size="2">Also if you have other sources where I can find information about that are appreciated.</font></div>
<div dir="ltr"><font face="Tahoma" size="2"> </font></div>
<div dir="ltr"><font face="Tahoma" size="2">Thanks, Klaus</font></div>
<div dir="ltr"><font face="Tahoma" size="2"> </font></div>
<div dir="ltr"><font face="Tahoma" size="2"> </font></div>
<div dir="ltr"><font face="Tahoma" size="2">Here are my questions:</font></div>
<div dir="ltr"><font face="Tahoma" size="2"> </font></div>
<div dir="ltr"><font face="Tahoma" size="2">1. How much time (overall) is needed to develop a file system like XFS from scratch?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">2. How many people are currently developing XFS in full time or part time?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">3. Have you developed a theroetical concept or was it more trial and error?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">4. If yes how much time did you spend on developing a concept?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">5. Have you (or others) been experienced in file system development when you started this project?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">6. Do you think there has to be at least one experienced developer to develop a file system like XFS?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">7. How does the effort split up (concept, developing, testing)?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">8. What is the most problematic part of developing file systems?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">9. Did you get help from other file system developers (which maintain their own file system)?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">10. Are there people from "outside" and ask for features?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">11. If yes dou you take them into consideration?</font></div>
<div dir="ltr"><font face="Tahoma" size="2">12. What's the most complex feature of your file system?</font></div>
